Types of Conventional Loans: Your Guide to Home Financing

Conventional loans are one of the most common and versatile mortgage options available in the United States and other Western countries. Unlike government-backed loans, conventional loans are offered by private lenders and follow guidelines set by financial institutions and government-sponsored enterprises like Fannie Mae and Freddie Mac. These loans provide competitive interest rates and flexible options for qualified borrowers, whether you’re buying your first home, upgrading, or investing in property.

This comprehensive guide will help you understand the various types of conventional loans, their eligibility criteria, advantages, drawbacks, and how to select the right loan based on your needs.

What Is a Conventional Loan?

A conventional loan is a mortgage that is not insured or guaranteed by the government. This means that the loan comes directly from private lenders such as banks, credit unions, and mortgage companies. Because there is no government backing, conventional loans tend to have stricter qualification requirements compared to FHA, VA, or USDA loans.

Most conventional loans adhere to guidelines established by Fannie Mae and Freddie Mac, which regulate loan amounts, credit score minimums, debt-to-income ratios, and other criteria to ensure loan quality. These guidelines help maintain stability in the mortgage market.

Key Characteristics of Conventional Loans

• Private Lending: Loans are provided by private financial institutions without government insurance.
• Loan Limits: Most conform to specific maximum loan amounts set annually, but some exceed these limits (jumbo loans).
• Credit Requirements: Higher credit score requirements compared to government-backed loans.
• Down Payment: Typically requires a down payment of 3% to 20%, depending on the program.
• Private Mortgage Insurance (PMI): Required when the down payment is less than 20%, protecting the lender in case of default.
• Loan Terms: Available in fixed or adjustable rates, with loan lengths commonly ranging from 10 to 30 years.

Types of Conventional Loans

Understanding the different types of conventional loans will help you make the right choice for your financial situation.

1. Conforming Loans

Conforming loans are conventional mortgages that meet the specific guidelines set by Fannie Mae and Freddie Mac. These include limits on loan size, borrower creditworthiness, and documentation requirements.

Benefits of Conforming Loans:

• Lower Interest Rates: Because they meet strict guidelines, conforming loans usually have more favorable interest rates.
• Easier Qualification: These loans are easier to qualify for if you have a good credit score and stable income.
• Wide Availability: Offered by almost all lenders, making them the most common type of mortgage.

Loan Limits:

In most areas, conforming loan limits are updated annually. For 2025, the limit for a single-family home is around $766,550, but this can be higher in high-cost housing markets.

2. Non-Conforming Loans (Jumbo Loans)

Non-conforming loans, commonly known as jumbo loans, exceed the conforming loan limits. Because they involve larger amounts, they carry higher risk for lenders.

Who Should Consider Jumbo Loans?

• Buyers purchasing high-value properties in expensive real estate markets.
• Individuals with strong credit profiles and substantial income.
• Borrowers who can afford larger down payments.

Key Differences from Conforming Loans:

• Stricter Credit Requirements: Typically require credit scores well above 700.
• Higher Down Payments: Often 20% or more down payment is required.
• Higher Interest Rates: Because of the risk, jumbo loans may come with higher rates and fees.

3. Fixed-Rate Conventional Loans

A fixed-rate mortgage maintains the same interest rate throughout the loan term, offering predictable monthly payments.

Common Terms Offered:

• 10 years
• 15 years
• 20 years
• 30 years (most popular)

Advantages:

• Stability in payments, making it easier to budget.
• Protection from interest rate increases.
• Ideal for long-term homeowners.

4. Adjustable-Rate Mortgages (ARMs)

ARMs start with a fixed interest rate for an initial period, then the rate adjusts periodically based on market indexes.

Typical ARM Structures:

• 3/1 ARM: Fixed for 3 years, then adjusts annually.
• 5/1 ARM: Fixed for 5 years, then adjusts annually.

When to Choose an ARM:

• If you plan to sell or refinance before the adjustable period begins.
• If you anticipate interest rates to decrease.
• If you prefer lower initial monthly payments.

5. Low Down Payment Conventional Loans

Some conventional loan programs allow down payments as low as 3%, making homeownership more accessible.

Examples of Programs:

• HomeReady by Fannie Mae
• Home Possible by Freddie Mac

These programs are designed to help low-to-moderate income buyers and first-time homebuyers.

Benefits:

• Small down payment requirements.
• Flexible credit and income criteria.
• Potentially lower mortgage insurance costs compared to FHA loans.

Qualification Requirements for Conventional Loans

Qualifying for a conventional loan requires meeting specific lender criteria designed to ensure you have the financial stability and creditworthiness to repay the loan. While exact requirements may vary between lenders, the following are the most common and important qualification standards:

1. Credit Score

A solid credit score is one of the most critical factors for conventional loan approval. Most lenders require a minimum credit score of 620, but borrowers with scores of 740 or higher typically receive the best interest rates and loan terms. Lower credit scores may still qualify, but often at the cost of higher interest rates or additional conditions.

Credit scores reflect your history of managing debt responsibly, including timely payments and the amount of outstanding debt. Improving your credit score before applying can significantly reduce your borrowing costs.

2. Debt-to-Income Ratio (DTI)

The debt-to-income ratio is a key metric lenders use to assess your ability to manage monthly payments alongside your other debts. It’s calculated by dividing your total monthly debt payments (including credit cards, car loans, student loans, and proposed mortgage payments) by your gross monthly income.

Lenders generally prefer a DTI below 43%, although some may allow up to 50% with compensating factors like a large down payment or significant cash reserves. Maintaining a lower DTI improves your chances of approval and can qualify you for better loan terms.

3. Down Payment

The amount you put down upfront affects both your loan eligibility and the cost of borrowing. Conventional loans usually require a down payment ranging from 3% to 20% of the home’s purchase price.

• 3% Down Payment Programs like HomeReady and Home Possible cater to first-time buyers or those with limited savings.
• 20% Down Payment helps you avoid private mortgage insurance (PMI), which reduces your monthly expenses.

Making a larger down payment can also demonstrate financial stability to lenders and potentially lower your interest rate.

4. Employment History

Lenders want to see consistent and stable income to ensure you can handle monthly mortgage payments. Typically, you need at least two years of steady employment in the same job or industry. Self-employed borrowers may need to provide additional documentation such as tax returns or profit and loss statements.

Gaps in employment or frequent job changes might require explanations and additional proof of income stability.

5. Property Appraisal

Before approving a conventional loan, lenders require an independent property appraisal to confirm that the home’s market value matches or exceeds the loan amount. This protects the lender by ensuring the collateral (the property) is worth the loan.

If the appraisal comes in below the purchase price, you may need to renegotiate the price, increase your down payment, or in some cases, the lender may deny the loan.

Meeting these requirements improves your chances of obtaining a conventional loan with favorable terms. It’s always recommended to review your financial situation and credit profile in advance and work with mortgage professionals to prepare a strong application.

Real-World Example: Choosing the Right Conventional Loan

Consider Sarah, a software engineer in Seattle, looking to purchase a $900,000 home. Since the price exceeds the conforming loan limit, Sarah opts for a jumbo loan. She has a credit score of 760 and puts down 25% to meet lender requirements. Her loan choice allows her to secure a competitive rate and buy the home she desires without government loan restrictions.
